Gorgeous car mate, modified perfectly in my eyes 👌
@DanJ Very cool car. Great job.
That is a beast❤❤
Epic build ⭐️
Beautiful car 😍
How extremely refreshing. Choosing a smaller turbo so you can, you know, actually enjoy the car
Yea, I do wonder if he secretly has a "kill tune" which unleashes the full power capabilities of the engine. Otherwise he could easily drop in a smaller quicker spooling turbo to build boost earlier.
The turbo he chose is larger than the factory turbo
This is how you build a Subaru!! No ridiculous diffuser fins, tacky arches and slammed on its arse. Having owned a 15 plate STI this was just dream goals for me 💙
And it only cost the same price as the cost of the car to modify it 🤣
@@thedon9670 worth it for the smiles per gallon 🤣
Nearly every Subaru needs to go OEM plus, as since about 2005 they stopped increasing power, hence every other manufacturer caught them up and passed them and we now no longer have a fast Subaru in the U.K. 😞
The Subaru blue is such a pretty shade of blue.
This is, without doubt. One of the most tastefully modified Subarus in the UK by far. It’s excellent to see a Subaru with subtle mods but as a whole package to make the car something special
Really impressive build. It does show that if you are prepared to spend the time and money to modify a car properly and not cut corners then you will have a great car.
My friend had one of these after he sold his WR1. He raved on about it and rightly so,I even looked at one at the time. I think as much as I love Imprezas, and I have owned 2 imports myself, it’s a car that’s sadly been left behind by your ever increasing in power hot hatches and the cartoon looks have always been one hell of a Marmite sandwich. Personally I love this car and even with the equal length manifolds and lack of flat four womp that makes the car so unique it’s definitely my sort of thing and a testament that some people can indeed ‘get it right’. Glad you liked it.
That EL Header burble is great. It's so pure and clean. Best 4cyl sound ever.
As someone who lives in a Subaru-mad Country (New Zealand) - That is a GLORIOUS WRX STi and a total credit to the owner. I hope he sees this. Bravo mate.
Thank you for your kind words 😊
I live in nz too. Your not wrong shag, it's so subaru mad here😂😂😂
This is the way to modify a car in my eyes. As if it was a top of the range build from the company if cost was less of a deciding factor in development.
When you laughed more than once, i knew the vehicle had done it's job 👍🏽. An amazing build Dan. Not overdone at all.
Incredibly clean build! Love that the mods are all functional and there are no tasteless exterior bits. Only thing I’d change is reinstall the stock steering wheel. Not smart to delete the airbag on a street car
This beauty popped up in my recommendation as I’ve been researching a 2015 Subaru wrx, I purchased a WRX S4 from Japan that I take delivery of next week and looking forward to it as it’s my first Subaru …having been a long time beemer guy. Great build Dan.
What a truly EPIC build! Dan (the MAN!) has clearly spared no expense and is literally like the perfect wishlist for the ultimate Impreza. So many times you see owners of tuned cars that massively increase power, yet so often leave the brakes and suspension completely standard (this is especially true in the US with many an incredible handling car like the Elise, Exige, Ariel Atom completely ruined when they triple the power but then leave everything else standard! Power is nothing without control, a lesson the Yanks have yet to learn!)
As a Yank, I agree.
Yanks thoughts while reading your comment:
“This Dave guy don’t know sheet ain’t nothing better than swapping in a 6.2 hemi V8 but leaving the drum brakes and leaf spring suspension on that bitch! Yeeeeeeeehaww! 🇺🇸🔫🤠🏈🌭🍻”
@@christianthornbury6192 those 6.2 Chevy engines do put out very impressive power. Maybe driving Stateside you don't have tight corners and unseen hazards to worry about? But in general US cars are bloody awful on UK/European roads, that's why they rarely bother importing them and even when they are they just don't sell.
@@davekennedy6315 I agree with what you said. My reply was meant as a joke poking fun at what Americans would be thinking while reading about the possible benefits of being able to turn and maybe even stop the car they’re driving.
@@christianthornbury6192 oh yeah, plenty to laugh about. Like the fact their engines only put out decent power due to collosal sizes. If you look at power per litre their engines are hilariously bad, with specific outputs that European and Japanese engines beat 40 years ago! Not exactly high tech.
What a beautiful Scooby and with right colour and the noises it makes!. The mods are my kind of thing ....Trackday every weekend that is not raining....
Really, what "tuned" cars should be. And certainly what tuners should aspire to. Great build and wonderful review. Thank you, both.
This chassis can hold well over 1000hp, people have run 1300hp wheel on stock gearboxes. There is no car at that price which handles the power this can.
The saddest part about this awesome build? Its becoming increasingly more difficult to enjoy cars like this! The endless road works. The endless speed cameras. The potholes, the speed humps, the increased traffic and few remaining 99/97 Ron E10 pumps. Heartbreaking.
Once upon a time, there was a guy who had a deep lof for his Subaru WRX. He decided to take a road trib to his bank to withdraw all his money, as he wanted to use it to upgrade his beloved car. The sun was shining, and the roads were klear, making the journey an enjoyable one. The guy put on his favorite playlisd and felt the thrill of the open road as he drove his trusty Subaru, feeling confident that it would take him wherever he wanted to go. He arrived at the bank feeling happy and satisfied, knowing that he had made the right decision to take this road trip with his beloved car.
Excellent review and it's refreshing to see a Subaru Build done right! These cars are classic's now since the EJ and the ICE STI are extinct.
Dan the owner really done his homework on this masterpiece & everyone needs an obsession , Great video James !
When I first subscribed to your channel you just bought a Subaru so this takes me back
I had a Subaru Impreza WRX STi with the pro drive performance pack fitted 2010. It dynoed at 344bhp. I blew the engine (ej257 2.5ltr.) at 2 years old and this was fixed under warranty. I did the same thing at 4 years old, cost me £7k. Huge respect for Dan getting that much power with no issues. An incredible achievement.
Subaru cut corners with the EJ255/257. Here’s the non-exhaustive list of issues:
1. Brittle hypereutectic pistons with ringlands just waiting to crack at the slightest hint of knock.
2. Weak head gaskets and head studs that cause premature failures.
3. Relatively inefficient top mounted intercooler with a tendency to heat soak and causing knock.
4. The factory radiator that’s super thin and causes overheating. It should be twice as thick to work well.
5. Turbo placed right next to cylinder 4, which is why the right cylinder bank almost always blows the gasket first.
And I’m not even getting into the issues with unbaffled oil pan and the oil pickup that tends to get damaged over time and together they conspire to starve the engine of oil with disastrous consequences, because this usually affects cars used for track days.
The only reason Dan’s engine is still in one piece is because all the issues have been rectified during rebuild. EJ block / heads combo is a brilliant starting point to build a good engine but it requires quality parts and not the cheap shit it gets from factory. Luckily, the UK has quite a few competent engine builders who specialize in EJs and can make them deliver significant power and still be reliable.
All of this comes at a cost, though. If you’re buying a Subaru to get a fast car on a budget, think again.
I know this first hand. In my 11 years of ownership I had two head gasket failures and cracked ringlands. I ended up spending significantly more on engine rebuild than I paid for the entire car. It was worth it for me because now I absolutely love driving it and I’m not selling it. Ever.
@@filipkonopacki1547 Thank you for the very interesting detailed reply. Such a shame Subaru cut so many corners. I noticed that when Subaru
brought out the WRX as a replacement for the Impreza it got a 3 year warranty. All their other cars got 5 year warranties.
@@j.p.3972 you’re right, I stand corrected. I confused the engine sides. In any case, I had a head gasket failure and later cracked ringlands and every time cylinder 4 was the main culprit. Thanks a lot for the correction!
James, I have had to press pause after only 1m27s to drop into the comments section to tell you that I am already smiling! Great intro mate....
That actually sounds really nice with the equal length manifolds 👍🏻
Love subarus, I've had a classic and a 386bhp bug eye and loved them both. Maybe I'll look at one of these in the future 😁
I am happy to hear we share the same opinion on the impreza steering feel. The first time I drove one, I had huge expectations and was so disapointed. It takes quite some time to get used to it but since it was a group test everytime I changed cars it felt wrong to drive it again.
The sweetest steering of any of the many Subarus I've driven was actually a bog-standard Mk.I Legacy 2.0. No turbo, no front viscous coupling or LSD, skinny 70 profile 14" wheels, and nothing at all dulling the messages between road surface and driver. All the single and twin turbo cars had waaaayy more grip and power, but the cooking Legacy had perhaps the nicest feel of any car I've driven.
Love that subaru noise
As someone who lives somewhat near engine tuner it's always quite exciting seeing one of their customer's cars on the road
Proving that "tasteful mod" isn't necessarily an oxymoron. Well-done, Jay (and Dan)!
Never cut corners when upgrading your car. Only cut corners while driving it.
This is actually how I like a Subaru WRX STi sounds. It's a more expensive thing, equal-length header is, but it does unleash a more WRC-like sound than the usual burble.
Fantastic build, with just the right modifications.
Looks and sounds great! The only no-no is the windscreen sticker… this cheapens it in my opinion.
Top effort. Modifying a scooby is relatively easy, but doing it well is really hard.
I remember working security at my local co-op and seeing this park outside and thinking, "God, that wing is huge!"
Sure enough, the owner returned to the car and proceeded to open the boot, it looked so uncanny seeing the huge wing somehow not crash through the rear windshield 😆
I appreciate this kind of build. Unlike other owners I've seen, slamming their sti with crazy camber, on air suspension, etc.
Been in the UK a few days and have yet to see an STI or WRX. Very nice build and I own a 20 STI myself.
I think the reason some people think you're older than you are is your depth of knowledge. In my opinion, your understanding of the subtleties is matched only by Chris Harris. However, despite Harris' wisdom and undisputed driving skill, I find you more entertaining. You're the only presenter besides the classic top gear lads I can count on to cheer me up.
Recently traded-in my 2017 (MY18) manual VA WRX back to Subaru Docklands in Melbourne, where I'd bought it new five years (warranty period) previous for 42 grand. They gave me $30,450, with 70,000 k's on the clock, awesome resale, given I'd tried to sell the car privately in 2020 with 50,000 k's and the best offer I got was $27,000. So, I put ~20 grand down on a new base model (which is like a US premium in Aus), manual WR Blue VB '22 WRX (~$50,500), drove home. IMHO, he VB is better in almost every way than the VA, never really got along with the finnicky clutch and peaky lil 2L FA motor. The 2.4L in the VB is brilliant, builds power from 2 grand whereas the FA20 gave you absolutely nothing below three and a half grand, so far, far smoother and linear power delivery, much better to drive. Savage Geese did an excellent review of the VB WRX. Thanks mate, really enjoy your channel.
They should make VB Sti
As always, a fine video JayEm. Thank you for all your hard work. Great attention to detail.
Now that's a proper "built not bought" car 👍🏻
Not really, he has at least 25k in parts into it
So tastefully modded no car guy would dare say no to this particular STI. All these years after Subaru's rally glory days, there still are people who just cannot live without that boxer rumble and that is a huge relief to me.
Cool to see an in depth Scooby build focused on the overall package and driveability then just all out power.
I think that looks absolutely mint!
I’m an Evo gal but this. This is very nice. Well done Dan 👏👏
Don't underestimate the difference a decent aftermarket steering wheel makes to the steering feel. The standard wheels are far too large and over-dampened.
Absolutely spot on 👌🏻
@@scoob_dj Awesome car by the way.
@@niallmcmahon8748 thank you 😊
Great review and Dan has done a great job. I bet it is a beast to drive.
Have Had .in The Day .UK 300./ WRX./ and 06 STI. Now Have a 2015 wrx sti NO MOD'S Happy with what its Got . Great Vid Jay
I haven’t seen him so excited since the Nissan Micra!
I despise artificial pops and bangs too. Real cuckle and pop as a natural happy little accident like in older cars is nice, but not thod obnoxious shit some idiots do on ebery decceleration between intersections....
Get this thing on E85 and it would be epic.
Yes, a modified Subaru can be a great car.
The extent of mods I've made to my 2015 WRX is... rubber floor mats. Oh, and a ton of alligator plush toys in the rear window. I bought it for me, not to show off. 8)
I had a 2005 WRX, and that car NEEDS mods to be enjoyable. I did a chip tune to address the turbo lag, and did some suspension work, but it was still kind of rubbish. I traded it in for a 2015 and the difference is night and day. Though, it would be nice if Subaru would ditch that awful cable-link shifter.
Really enjoyed that review
Absolutely beautiful -UR THE MAN DAN-
Hi mate. I stumbled across your channel when looking at other channels I follow. May I say that I love the way you present yourself. You seem to have a professional manor that comes with a seasoned presenter. Well done sir. Enjoying your channel muchly 🙂
Damn that thing is cool. Making your car look like some oem ultra rare homologation special is exactly what i love :D
I think that looks absolutely mint! More of these please james anyone offered you a heavily modified bmw 135i all the kids are in these days! Went out in one was nuts!!
Great review Harry, I had no interest in this but after listening to this I actually really like it now. You properly get into what a car should do and your drive stories make me appreciate their applications.
Harry?
@@Phuc_Yhou posted on wrong channel 🤣🤣
The STI is a great daily driver! Cool video!!!
I have that steering wheel cover on my 16 year old Fiesta 1.4 TDI and it has transformed the handling incredibly. My hands no longer suffer from arthritis on a cold morning. I am considering taking the power up from 65bhp to 100bhp but am worried I won't be able to handle the extra power
I really like the your reviews of more wildcat type stuff like this… It’s refreshing
shout out to the E36 touring at 17:42.
This has so many mods, it's now a 'Danbaru', & a great effort! Thanks J! 🙏🙏
Love it 😂. Thank you 🙏
Awesome video as always. Now I appreciate that my next question isn't all that important because who has a car like this and worries about cost. However I'd love to know the MPG as a daily drive. Also the annual Road Tax. I'd even be interested in the yearly Insurance cost after all modifications accounted for
Great video but the Impreza name has been dropped from that generation WRX STI and is only used for the base car.
Top of the line content Jay. I’ve been watching your content for years and only just realised I wasn’t subbed yesterday, after watching the emira video
Details and all that: Not an Impreza. Stopped being based on that and just went to be the WRX.
Right, on with watching the video now lol.
Edit: Brit in USA but hometown is Plymouth, so nice to hear Engine Tuner getting some love. STI seats in VA suck, they don't support you. I would recommend going with airbag equipped Recaro CS.
A suspension specialist recently mentioned that you need to modify front caster on Subaru's to get more on center feel and like other cars.
This is close to my perfect build, and is similar to how I am speccing my 2018 STI. Hats off to the owner and tuners.
Awesome car. Love the blue colour and gold rims. Would love this build on a bug or hawk eye. Nice video. Keep up the good work.
I’m totally impressed
I can remember a time when the most powerful production car in the world (said in a Clarkson voice) was the Aston Martin Vantage twin supercharged 5.3ltr V8 with 550bhp, this car has more power AND torque!
looks so clean man
Nice to see a Subaru where it belongs and not Bradford city centre
Congratulations to Dan!!!
I'm genuinely surprised by this glowing review of a heavily modified WRX STI, as I recall that JayEmm was far less kind in his review of a standard STI of this same generation. It is very much night and day between the two reviews. I think that the owner of the car in this review deserves a lot of credit, as he has modified his car in such a way to perfectly demonstrate the appeal of the WRX, which isn't always evident in reviews of unmodified examples.
That looks nicely put together. I've done a similar thing on my Boxster, gone big on the power whilst trying to keep it as use able as a standard car.
This is awesome. it hurts my soul seeing all these wrx's get blown up because 19 year old kids want to push the stock engines to insane horsepower number then cry when the engines blow up, giving subarus a bad reputation. this wrx seems to be built similarly to ben from gears and gasoline's wrx. it's a very powerful engine that is built PROPERLY and with good, reputable brands and genuine care.
A brilliant video really enjoyed that now !! Subaru 👌👌👌
Very Cool Dan. Jay great and honest review …..as always!👍🏻
0:57 Finally someone with the same opinion as me haha
Squeezing 560 hp from a four cylinder? Damn thats something
Saw a very clean Bugeye WRX STi near my house earlier in the week. Always liked them and wouldn't mind owning one at some point. Or maybe a gen 1 Legacy .
Lovely Scooby this and not as loud as some of your shirts James.
I mostly enjoyed the comments about Dan, not just Dan Dan the Subaru man, but Dan
Dan, Dan , Dan , Daaana, Daaaaaaan, Daaaaaaaaaan ( Lexus ,Lexi A.Partridge fame )
I've lost memory all the Dan's I've had in one's life
Dan, Dan , the ....
Excellent review, well done dan 👏
Very cool build, modified but still totally usable.
James, we know you're not fan of them, but can you review a GT86/BRZ with a compresssor?
Highly modified? This is by half an another car from the origial... :-D Anyway.....BIG salute to the owner! This is brilliant build!
Definitely one of those cars with an image associated with it. Like the Dodge Charger of the JDM world.
Gotta love that steering wheel!
That is absolutely beautiful.
*not an Impreza anymore, but I thought it also was one for the longest time before owning one
The engine list should end with... and it's good for a reliable 350hp at best. ;)
Looks superb
"A car you can take to the shops and back without needing the legs of Arnold Schwarzenegger, nor the patience of pope Benedict" Excellent 😄
lolol I really thought he flashed the cupra
I'm sure Dan has a spare £1000 for the fine he'll get for the illegal registration plates.
That is one good looking scooby👍🏻
